There’s a topological theorem that proves hair has to have a singularity — an area it radiates from. What you’re calling the “bald spot” is a combination of this theorem and a standard problem in photography — certain angles make the hair appear thinner.

The singularity is what causes Dennis the Menace’s cowlick and why Donald Trump’s hair looks like something not of this universe.

Luke might be going bald, but you can’t tell from this picture. Check several pictures and see if the “bald spot” moves. This one appears off to the side, which is what makes me suspicious.

I went through my photos from the East Hills High Rise Implosion and none of them give the impression that Luke’s going bald. He does have a very short haircut, which will make just about anyone appear bald from a great variety of angles.

If he is, he really ought to consider minoxidil — if this photo indicates he’s going bald, it’s in a way that minoxidil can often treat.

BTW: If you’ve ever heard the expression “Black holes have no hair,” then you’ve been exposed to this topology theorem through your astrophysics. Black holes can’t have “hair” (a magnetic field or anything with poles) because the singularities the hair has in being combed would give you further information on the interior of the black hole beyond mass, charge, and rotation.
